IMPROVEMENT IN WATERCLOSET VALVES.

The Schedule referred to in these Iietters Patent and making part of the shame.

Toy all whom it 'may concern Be it kuown that I, JACOB N. DEoK, of the city"v of Buffalo, in the county of Elie, and State of New York*l have invented a certain new and improved Water-Closet Valve; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, making part ot" this specification.

My invention relates to that class of water-valves in which the valve is opened by means' of a piston-rod, and automatically closed by the action of a spiral spring, when the force applied to the actuating-rod is removed.

My invention consists in the use and arrangement of a hollow or compressible rubber, or other elastic ball, which, in its normal situation, presses against the valve-seat, and shuts oi the dow of the water, and which is removed from contact with its seat by being compressed by a piston-rod, the elasticity of the ball causing it to resume its proper shape and position against the seat, when the pressure is removed, thereby automatically closing the valve, and shutting o the escape.

In the accompanying drawings- Figure I is a section of my improved valve, in line of the actuating-rod, and through the induction and eductionpassages. Y

Figure 1I is a cross-section of the valve, showing the induction-ports, and bearing-surface opposite the valve-seat.

Figure I'II is a section at right angles to that of Fig. I, and in line a: x of that figure.

Like letters of reference designate like parts in each of the figures.

A isthe rubber ball;

B, the valve-case;

C, the induction-passage;

D, the eduction-passage E, the piston or actuating-rod; and, F, the shank which securesA the valveto its support, G, inthe ordinary manner.

The valve is cast in vtwo portions, to permit thefintroduction of the ball, the half opposite-the valve-seat, h., being provided with a bearing* surface, t', which presses the ball against its seat, when the two parts of the case .are screwed together. V

Outside of this bearing e', are formed the ports mm,

vthrough which the water fromthe iuductionfpassage enters the valve-space n, surrounding" the ball, which only lpartially lls the case, as shown.

P represents the packing for the piston. q, a collar formed ou the latter, to prevent its ward withdrawal from the valve; andA s,.an adjusting-head, by which 'the length of the rod 'can be regulated in adapting the valve to the various forms of water-closets, to which it is applicable.

The operation of my valve, constructed as before described, is obvious. y I

1 The ball beingvin the position shown in Fig.I, prevents the water, which enters the valve through the ports m, `from escaping, until the ball is unseated by the pressure of the. piston, which partially compresses it, or vcauses it to collapse' sufficiently to permit the How of the liquid.

The .great and manifest advantages of my imp rove- Ament are its cheapness, simplicity, durability, and non-liability to get out of order.

What I claim as my invention, and desire to secure by Letters-Patent, is-

'lhe rubber or other elastic ball A, arranged with the seat h and bearing t', so as to be pressed from the valve-seat by a thrust, substantially as set forth.
